[Discuss-gnuradio] Tx Amplitude in USRP N210

2011-09-28 Thread Konstantinos
Hi, I am trying to find out how to set the TX-amplitude parameter between 0-1, which is given as an option in USRP sink. My attempts to find a clear explanation of this parameter have all failed. Also, I would like to understand how to set the receive SNR in the source file? As for the

[Discuss-gnuradio] Bandwidth of XCVR 2450 Daugtherboard

2011-09-28 Thread Konstantinos
Hi again, I recently found out that the Bandwidths of the XCVR 2450 Daugtherboard are as follows for the RX and TX side respectively: Bandwidths (Hz): RX: 15M, 19M, 28M, 36M; (each +-0, 5, or 10%) TX: 24M, 36M, 48M Can someone elaborate on these values please and how to decide upon

Thanks for your reply. However, I am a little bit confused since in your reply you mention that these are programmable low-pass filters which operate at baseband, while in the code the associated comment says that this is the bandwidth of the bandpass filter on the board. Secondly, why are these

[Discuss-gnuradio] USRP network based spectrum analyzer

I have a usrp and computer in a remote location without much network bandwidth available to the system and I'm using it as a spectrum analyzer. I'd like to run the fft on the remote system and then send the results to a connected client for display. This would allow me to get greater fidelity
